Dark skies

Find the dark

The difference between a city sky and a truly dark one is the difference between a dozen stars and four thousand. Vantage maps light pollution so you can find the nearest Bortle-1.

The Bortle scale

class 8   city — the moon washed out
class 4   suburbs — milky way faint
class 1   wilderness — milky way casts shadows

Why it matters

One night under a Bortle-1 sky will ruin city observing for you forever. In the best way.
